Configuration and Operation (cont.)
DIP switch configuration
WARNING: AC and DC connections must be isolated during DIP switch configuration. The correct battery type
and cell number must be configured correctly before charger power-up and battery connection. Incorrect
configuration may result in under or over charge of batteries, which may cause failure or damage to the batteries,
charger and connected equipment, and result in serious personal injury.
All Sentinel models include a 6 way DIP switch for configuration of battery type and cell number. The DIP switch is accessible
through a cut-out in the case rear:
Open frame SNTL models Enclosed ESNTL models
DIP switch functions :
1 – 4 Sets the charge profile (battery type and cell number) when ‘local’ mode is selected – see switch 6 below.
5 Sets whether the Sentinel charge profile is set in local or remote mode:
Local mode: charge profile set by DIP switches 1 to 4. The default setting is
‘Local, Auto’, where Sentinel auto-
matically selects 12 or 24V operation based on the battery voltage measured at power up – see ‘operation’ below.
Remote mode: charge profile set by remote RS485 communication (e.g. SNTL300P-PCSUITE software), or (on
LCD models only) using display menu options. When remote mode is selected, the default charge profile is ‘Auto’.
6 Reserved use. Do not adjust from default (0/off/down) setting.
